AI Explanation
The correct answer is C) 11. The electrical schematic symbol represented by option C) 11 is the symbol for a normally closed limit switch. A normally closed limit switch is an electrical switch that is closed (conducting) when the switch is not actuated, and opens (non-conducting) when the switch is activated, such as by contact with an object. The other options do not represent a normally closed limit switch. Option A) 6 is the symbol for a resistor, option B) 10 is the symbol for a normally open limit switch, and option D) 14 is the symbol for a push-button switch.
